BACKGROUND

1. Field of Endeavor

The present invention relates to stable, concentrated, aqueous and water-soluble fertilizer suspensions formulated to provide plant nutrition for growing plants, and more particularly to stable, concentrated, aqueous and water-soluble suspensions of mineral salts and nutrient additives.

2. Description of the State of the Art

For healthy and rapid growth, particularly in a hydroponic environment, plants require a nutritionally balanced soluble nutrient feed program. Some liquid mineral fertilizers comprising mineral salts have limited solubility in water. Additionally, some of the elements required for plant growth form insoluble compounds at low concentration levels that precipitate. Liquid fertilizers typically contain the major macronutrients of nitrogen, phosphorous, and potash and the micronutrients: iron, manganese, zinc, copper, boron, molybdenum and frequently omit the intermediate elements of calcium, magnesium, and sulphur. When using liquid fertilizers of this type, one can experience imbalanced growth and nutrient deficiencies in the plant. Liquid fertilizers may be accumulated to provide complete plant nutrition for growing plants. For example, in order to achieve a complete nutrient profile, the feed program may include at least two nutrient containers of ionic nutrients to avoid or minimize precipitation of ions prior to their application to the target hydroponic culture. A well known formulation for solutions in which plants may be grown in hydroponic cultures is Hoagland's solution where a first solution includes potassium nitrate, calcium nitrate, monopatassium phosphate, magnesium sulfate, an iron chelate, and a second solution is a micronutrient stock solution that includes boric acid, manganese chloride, zinc sulfate, copper sulfate and molybdic acid. In addition, Hoagland's solution may achieve a lower pH by the application of ammonium. To apply the Hoagland's solution, this two-solution or two-container approach requires that, in order to provide a complete nutrient feed, one must mix two separate concentrates and dilute each in a user solution to avoid precipitation. From a commercial distribution perspective, one may have to ship sufficient water along with the concentrate in that the water increases handling costs over just the necessary feed.

As an alternative to aqueous suspensions, dry nutrient blends may not contain the full gamut of minerals of a complete solution, and dry nutrient blends may not be completely water-soluble. In hydroponic systems having nutrient monitoring, the effects of the application of a dry nutrient blend to the hydroponic culture may be measurable and affect the subsequent frequency and amounts of the dry nutrient blend that may be added. If the dry nutrient blend is to be dissolved in hydroponic culture comprising cold water, several minutes or several hours may be required to achieve a complete dissolution. This cold water delay injects a non-negligible delay between recognizing the need for an application of a solution feed and actually delivering the solution feed. Likewise in bulk applications of the dissolved dry nutrient blend from a dilution container, several minutes or several hours may be required prior to administering to plants. Furthermore, many dry formulations that contain all the nutrients generally recognized for plant growth are hygroscopic, and absorb moisture from the atmosphere, and may eventually turn an original dry formulation exposed to atmospheric moisture into a sticky paste or one or more solid chunks that may be impractical to measure and dissolve. In addition, a complete dry nutrient blend may be mixed with water to form a liquid suspension and stored in a sealed container which may not exhibit sufficient shelf life. For example, an adverse gaseous chemical reaction may set up over several days that can cause the sealed container to swell, rupture, and leak a brine solution. Thus, a complete dry nutrient blend may be mixed with water to form a liquid suspension, but may be unstable and unsuitable for manufacturing and packaging in sealed storage containers.

Aqueous fertilizer suspensions producing particles that may settle out while on the shelf include the teachings of U.S. Pat. Nos. 3,519,413, and 3,950,159, both of which disclose a suspension of coarse particles and a hydrophilic or a polysaccharide gum for thickening. U.S. Pat. No. 4,069,034 describes a method of making a suspension fertilizer with bentonite and humic acid as crystal growth modifiers. The teachings of this disclosure are directed to a manufacturing process that deals with supersaturating nitrogen and phosphorous in a reactor at elevated temperatures. U.S. Pat. No. 4,525,197 discloses a fertilizer suspension that utilizes magnesium-aluminum silicate as a stabilizer along with a dispersant selected from sorbitol, polyvinyl alcohol, caseinate, and soluble starch hydrolosates to prevent the formation of large crystals. U.S. Pat. No. 5,851,260 discloses a suspension fertilizer suitable for irrigation fertilization and a process for its preparation, and its teachings to not appear directed to a complete fertilizer, having exemplary solutions made from relatively inexpensive, i.e., field grade, fertilizer raw materials with known water insoluble compounds not readily applicable to hydroponic cultivation. U.S. Pat. No. 5,997,602 discloses a method of manufacturing an aqueous fertilizer suspension containing at least phosphate, and calcium and magnesium ions, and its teachings appear to address suspensions that may or may not be nutritionally complete, and producing an inexpensive, i.e., field grade, fertilizer with insoluble material acceptable for a drip irrigation in field use, and where the exemplary form of nitrogen taught is urea. Because water-soluble mineral nutrients are derived from mineral salts, there is an equilibrium point for these salts to form crystals and for the crystals to slowly dissolve back into solution. Because large crystals form at the expense of smaller ones, i.e. Ostwald Ripening, there is a progressive tendency to grow water-soluble crystals in the concentrate. Such water-soluble crystals may eventually grow quite large and sink to the bottom of the suspension. These are particularly troublesome with mineral salts that have a wide range of solubility over different temperatures. This is particularly troublesome with potassium nitrate and urea.

A technique in the formulating arts is to use a cosolvent that is miscible with the solvent that lowers the solubility of the mineral salt and slows the rate of crystal growth. The problem is that few cosolvents are non toxic to plant growth. Another technique to overcome this is to create a non-aqueous suspension as disclosed in U.S. Pat. Nos. 5,707,551, 5,906,962, and 6,743,756 and as described in US Patent Application No. 2002/0065198 A1. U.S. Pat. No. 5,707,551 describes non-aqueous suspension concentrates of highly water-soluble solids where the liquid composition is completely non-aqueous and also requires a complex three-component surfactant system. U.S. Pat. No. 5,834,533 describes stable suspension compositions where the liquid composition is non-aqueous and the application is directed toward well drilling fluids. U.S. Pat. No. 5,906,962 discloses a method of non-aqueous suspension concentrates of highly water-soluble solids. U.S. Pat. No. 5,906,962 is a continuation-in-part of U.S. Pat. No. 5,707,551 based on a non-aqueous solvent and a complex three-component surfactant system, and appears directed toward suspending a slightly water-soluble active compound, e.g., pesticide or herbicide, with a water solubility of less than 1%. U.S. Pat. No. 5,925,182 describes stable liquid suspension compositions, some having limited solubility; a non-aqueous liquid suspension appearing to be directed toward well drilling fluids. U.S. Pat. No. 5,969,012 discloses non-aqueous slurries of water-soluble polymers, where the solvent is non-aqueous and is a vehicle for concentrated water-soluble polymers. U.S. Pat. No. 6,743,756 describes suspensions of particles in non-aqueous solvents, and appears to be directed toward the use of a castor wax as a stabilizer.

DETAILED DESCRIPTION

A method of formulating and stabilizing a concentrated, complete, nutritionally balanced, readily available water-soluble fertilizer is described. The composition of matter that results from the method embodiment includes all thirteen elements required for plant growth. The exemplary form of the nitrogen may be predominantly that of a nitrate anion for rapid nutrient uptake.

In describing the properties of the concentrate embodiments of the present invention, particular terms are used to address some of these properties. A stable concentrate is one that when stored in a closed container over a period of time, there is no adverse gaseous chemical reaction that causes swelling of the closed container. A homogeneous concentrate is a liquid concentrate that is a stable dispersion that, over a period of time, does not stratify into one or more solid layers and one or more liquid layers having the notable absence of large crystal growth. A complete concentrate is a concentrate having all nutrients required for plant growth present in a balanced form. A water-soluble concentrate is a concentrate having all of its elements readily available for plant uptake and do not need to be digested by microorganisms or undergo any type of weathering or degradation process. A pH balanced concentrate is a concentrate having a ratio of cationic and anionic forms of nitrogen balanced such that the predominant form of nitrogen is in the nitrate form, which is readily available, and not phytotoxic, to the plant. A non-toxic concentrate is a concentrate having no ingredients or additives in its blend that are phytotoxic to plant growth. A concentrate having no inert water insoluble material is a concentrate where all ingredients of the concentrate are readily dissolvable in water and available for plant uptake.

If one adds seaweed, digested plant material, soy protein, Kraft lignins or sulfate lignins, or other similar organic compounds, one can prevent the occurring of off-gassing experienced in the hydrating of dry fertilizers thereby making a stabilized formulation. Formulations having such organic compounds added to the formation have remained stable in the bottle for over 72 months. If seaweed is used in the blend, there are added benefits that may include shelf stability and plant absorption. If soy is used, there are added benefits that may include amino acid nitrogen and chelation effects. Additionally, the organic compounds further aid in the physical stabilization of the suspension, and maintain a homogeneous blend. Accordingly, if the water level is reduced to a practicable minimum and the particles are ground into the micron range, a concentrated stable dispersion is created that has a relatively long shelf life.

Accordingly, exemplary mix embodiments include an organic stabilizer derived from digested plant material or natural seaweed where the organic stabilizer may prevent off-gassing and swelling of the fertilizer container. The ingredients for the suspension are preferably readily soluble and have very low heavy metal contaminants. The water content of the dispersion is preferably controlled carefully in order to maintain a homogeneous blend that has excellent storage capacity and minimal crystal growth. The suspension may also contain additional natural and synthetic polymers to aid in stabilization of the dispersion. In addition, a humectant such as a water-soluble glycol may be added. The suspension exhibits excellent storage capabilities and readily dissolves when dispersed in water. The formula is well suited for hydroponic cultivation of crops as well as plants grown in soil-less or soil-free media. Additionally the preparation is useful for providing a complete balanced plant nutrition program for growing all types of cultivated crops in all types of growing mediums.

The invention, in its several embodiments, allows for a stable pourable homogeneous liquid concentrate well suited for growing plants in that the concentrate is nutritionally complete, water-soluble, pH balanced, non-toxic, and contains no more than trace inert water insoluble material, and the concentrate may be stored in a closed container. The embodiments of the invention may be applied to plants being grown hydroponically and embodiments of the invention may be applied to plants being grown in a soil matrix. The ratio of ammoniacal nitrogen to nitrate nitrogen is kept between 10 and 25%, it does not cause a rapid rise or decline in rhizosphere pH. This helps to maintain a balanced pH in the soil solution so that the solution is kept from wandering below pH 5 and above pH 7. There can be additional ingredients such as phosphates, citrates, carbonates and other organic acids to help buffer and stabilize the solution pH. An additional benefit of highly refined water-soluble mineral salts is that they are relatively free of heavy metal contamination and thus pose little risk to the environment and health of the consumer. The composition may be varied to alter the balance of nitrogen, phosphorous, potassium, and other elements, in order to allow for custom nutrition formulas for vegetative, flowering, and fruit development. The composition may also contain humic and fulvic acids, organic acids, enzymes, simple and complex sugars, vitamins, and growth hormones. Additional formulations are possible, for example, the incorporation of urea as a nitrogen source to lower the cost of production, without straying from the original spirit of the invention.

A concentrated complete nutritionally balanced readily soluble suspension fertilizer containing all thirteen elements required for plant growth comprising water-soluble mineral fertilizer salts and an organic stabilizer to form a stable dispersion may be made according to the following teachings. The mineral salts of the concentrated suspension fertilizer may be selected from a group of mineral salts comprising: ammonium nitrate; ammonium phosphate; ammonium sulphate; calcium nitrate; calcium phosphate; calcium sulphate; magnesium nitrate; magnesium phosphate; magnesium sulphate; potassium nitrate; potassium phosphate; potassium sulphate; iron sulphate; iron phosphate; iron glycinate; iron lignosulphate; chelated iron such as iron chelated via ethylene-diamine-tetra-acetic acid (EDTA), and/or iron chelated via diethylenetriamine pentaacetic acid (DTPA); and urea. The organic stabilizer of the concentrated suspension fertilizer can be selected from: digested plant material, digested lignin, soluble seaweed, beet vinasse, molasses, water-soluble hydrocolloid polysaccharides, compost tea extracts, vermicompost, cellulose, chitosan and mixtures thereof. Additional polymers of natural and synthetic origin to aid in steric stabilization of the mineral particles of the concentrated suspension fertilizer may be selected from the group consisting of gum Arabic, alginic acid, cellulose ethers, lignin sulfonates, condensation products of napthalenesulfonic acid, poly(ethyleneglycol), poly(propyleneglycol), polyvinylpyrrolidone, poly(vinyl alcohol), polystyrene sulfonate, poly(acrylic acid), poly(metacrylic acid) and block polymers of ethylene oxide and propylene oxide. The concentrated suspension fertilizer may include natural surfactants and synthetic surfactants such as lecithin, and TRITON™ X-45 and TRITON™ X-100 which are manufactured by Union Carbide Corporations of Danbury, Conn., USA. The concentrated suspension fertilizer may include a humectant such as glycerin, ethylene glycol, diethylene glycol, polyethylene glycol, propylene glycol, ethylene-propylene block copolymers and mixtures thereof. The total mineral salts concentration of the concentrated suspension fertilizer is preferably between 50 and 95%. The organic stabilizer concentration of the concentrated suspension fertilizer is preferably between 0.1 and 50%. The water-soluble polymer of the concentrated suspension fertilizer is preferably between 0.01 and 5%. The viscosity modifying surfactant of the concentrated suspension fertilizer is preferably present in the amount of 0.001 and 1%. The humectant of the concentrated suspension fertilizer is preferably between 0.1 and 25%.
